Explanation:
Repulsion and attraction
Two charged objects will: repel each other if they have like charges (they are both positive or both negative) attract each other if they have opposite charges (one is positive and the other is negative)
The answer is: molecular polarity.
Paper chromatography is an analytical method used to separate colored substances.
Substances are distributed between a stationary phase and a mobile phase.
Substances have different chemical structures and because of that, the different polarity, so each molecule have a different solubility in the solvent.
If a substance is very nonpolar, it will not dissolve at all in a very polar solvent.
If water (polar substance) is a solvent, the more polar the color, the higher it will rise on the papers.
Energy cannot be created or destroyed, so the answer would be c.) not a or b.
